I can't tell from the room / suite listing for this hotel what the base entry suite is so not sure if the SoCal Suite is the right one for application of upgrades. Also, I don't think that suites have the same policy as base entry rooms (if available for revenue stay - available for awards/upgrades) - I tend to think that it's not. Perhaps you can PM the Gold Passport Concierge staff here on Flyertalk to get the best answer.
